We bring sellers and producers together in one dashboard
Custombull is one dashboard for Etsy, Shopify, eBay and Amazon sellers that covers everything from finding trends to shipping. Our partner producer network in the US handles the printing.

Every step of selling in one place
Selling a t-shirt takes a lot of work: finding a trend worth selling, creating the design, preparing the listing, making sure the design doesn't infringe on anyone's copyright, getting the product onto every channel, collecting orders, and arranging printing and shipping. Custombull brings all of this into one dashboard. Custombull does not print anything itself; orders are printed by the best-suited producer in our US partner network.
- Trend research, AI-generated designs and automated production
- Listing SEO fixes and copyright checks
- Product transfer between all your stores
- Order management, printing, packing, shipping and a tracking page

7 steps from idea to delivery
- 1Idea
The idea engine scans what customers are searching for and what is trending; ideas pass copyright and platform policy checks.
- 2Design
AI generates the design, or the seller uploads their own; the product and variants are chosen and the copyright check runs.
- 3Listing and sync
An SEO-ready listing is prepared and transferred between Etsy, Shopify, eBay and Amazon. Drafts first, published on approval.
- 4Order
The buyer purchases, and the order arrives in the dashboard. Orders from the same customer are combined.
- 5Print file and printing
The right design file for the order is found automatically, and the best-suited partner producer in the US prints it.
- 6Quality control
The quality of every item is checked and guaranteed.
- 7Delivery
Over the last 60 days, half of all orders shipped in under 2.8 days. The buyer follows the order in their own language on a tracking page branded with the seller's store, and sends questions and personalization requests from there.
Why a partner producer network?
Instead of depending on a single print shop, we work with a network of partner producers in the US. Each order is printed by the best-suited producer. We ask every producer to meet the same quality standard, because our promise to sellers is clear: if a customer receives a defective item, you get a no-questions-asked refund or the item is reprinted for free.

- Quality control and a guarantee for every item

How we work
You see every AI-suggested change first. Nothing changes in your listing until you approve it, and applied changes can be undone.
We check and guarantee the quality of every item printed by our partner producers. If your customer receives a defective item, you get a no-questions-asked refund or the item is reprinted for free.
The numbers on our site come from our system records. We don't promise what we can't back up.
When you have a question, a real person answers.
Cost, address and internal notes are never shown on your customer's tracking page. Team members get only the access they need.
